Hi folks -- I am pleased to announce the public release of Tetro Domain, a small strategy game playable on desktop web and mobile: puleo.itch.io/tetrodomain

As I mentioned in a previous post, this game is built around the concept of the strategy-stealing argument: its rules have been designed so that there is a nonconstructive proof that the first player always has a winning strategy on any board the game can generate. As the proof is nonconstructive, it does not actually provide any indication of what the winning strategy *is* -- but I believe it ends up being an interesting little strategic challenge to work out the winning strategy that is guaranteed to exist.

The computer opponent you play against is not *especially* strong, but I've found it to be strong enough to sneak out the occasional win against me if I let my guard down. I'm biased, of course, but I've found playing it on mobile especially to be an entertaining way to get a quick strategy fix within a couple of minutes.

I think that *probably* the strategy-stealing argument could be pushed much further to a game with more complexity than this game has -- this design is fairly simple but I'm quite pleased with how it came together.
